1) will 10 bulbs in series mean that the last bulb is dimmer than the first?

2) are my calculations correct when i say that the 3 rows of LED's will draw 3.2v each, thus a total of 9.6v per group is used. 12v - 9.6=2.4v 2.4V x total of 200mA = 480Ω resistor needed per group...right??

please excuse any 'noobness' in above post i have VERY little idea but i am trying to learn!! this project may seem impractical due to cost but i just want to have a go at building a light circuit. i can solder....sort of! enough to join wires...this project is gonna be a little fun i think!!
